How to design a circulating water tank
Thread Content
I want to add a circulating cooling water tank to the device; I’m not sure about the aspects to consider for its design. I’d appreciate some advice from the friends on this forum.
1. Calculate the required heat transfer amount. 2. Calculate the required cooling water volume. 3. Determine the water tank capacity. 4. Select pumps and valves and determine pipeline specifications. 5. Perform resistance drop calculations to determine whether the selected pipe fittings and other components meet the requirements.

The circulating water tank has water entering and exiting at the same time; hot water that enters the tank needs to be mixed with cooler water. By what factor should the storage capacity of the tank be estimated?
According to relevant standards, the volume of the water tank is usually around 5% of the circulation flow rate!
4# zhuhonl Thank you!
I helped you solve the problem – why isn’t there a rating?
4# zhuhonl: If the flow rate of the circulating water is 0.6–0.8 m3/h, what should be the volume of the water tank?
With such a low circulation rate, the size of the water tank can be determined freely depending on its installation location. The tank volume can now be set based on a 30-minute buffer capacity, which is 0.4 cubic meters.
8# zhuhonl Oh, thank you!
8# zhuhonl didn’t read your reply carefully; I thought only moderators could give ratings
I’m sorry, may I ask which specification applies to the design of circulating water tanks?
